I remember those WH tie on boom connections well, also the loud crack noise emanating from the crushed mast as you rotated the boom down to perpendicular to get it into sailing position if you went a tad too tight on the loop. they were state of of the art for a time in the pre carbon late 80's but hey, I loved my '77 Chevy blazer when gas was 60 cents a gallon. As has been said, move on to a clamp on, why set yourself up for being stranded offshore with a broken mast.

That's why they came out with those thin aluminum mast shims to be placed where the boom attaches, to spread out the compression. Then you'd have to put some duct tape around the mast just below the shim to keep the assembly from slipping down the mast while sailing.
Those were some pretty heady, high tech days back then.
Buy a clamp on front end, and be done with it.
